Range hoods are indispensable helpers in modern kitchens, ensuring clean air by removing cooking fumes, grease, and unpleasant odors. But how exactly does such a device work? This article will tell you everything you need to know about how range hoods function and the different types available.

A range hood is an appliance installed above the stove to extract cooking fumes, smoke, and odors from the kitchen. It typically consists of a metal housing, a filter, and a fan. The appliance helps maintain good air quality in the kitchen by filtering pollutants such as grease and water vapor from the air.

There are various models of extractor hoods that differ in their functionality:

Exhaust air operation

• How it works: The steam is directed straight outside.
• Advantage: Very effective at removing fumes, grease and odors.
• Disadvantage: Connection to an exhaust pipe is required, which is not possible in every kitchen.

recirculation mode

• How it works: The air is cleaned by filters and then released back into the room.
• Advantage: Easy installation, as no exhaust pipe is required.
• Disadvantage: Less effective than exhaust air operation, as the air is not completely removed from the kitchen.

Combined operation

• How it works: Some extractor hoods offer both an exhaust air and a recirculation mode, so that you can switch between the two as needed.

Range hoods are indispensable appliances in modern kitchens, ensuring clean air by removing cooking fumes, grease, and unpleasant odors. But how exactly does a range hood work? This article will tell you everything you need to know about how range hoods function and the different types available.

The extractor hood works in several steps to clean the air:

Extraction

• The hood draws air in from above the cooking surface. In doing so, it captures steam, grease droplets, and other particles produced during cooking.

Filtration

The intake air is passed through different types of filters:

• Grease filters: These filters trap droplets of grease produced during cooking and prevent grease from settling on the walls of the kitchen or in the ventilation ducts.

• Activated carbon filters (in recirculating models): These filters absorb odors and chemical contaminants released during cooking, thus ensuring fresh indoor air.

Exhaust air or recirculation

• In exhaust air mode , the cleaned air is routed to the outside via a pipe system.
• In recirculation mode, the air is returned to the room after cleaning.

Filters play a crucial role in the functioning of the extractor hood. There are two main types of filters:

Grease filter

• Material: Grease filters are usually made of metal (aluminum or stainless steel) or plastic.
• Function: These filters trap grease and other particles from the air before they can settle on walls and appliances.
• Maintenance: Grease filters should be cleaned regularly or, depending on the model, replaced to ensure optimal performance of the extractor hood.

activated carbon filter

• Material: Activated carbon is used in these filters.
• Function: These filters absorb odors and chemical contaminants produced during cooking.
• Maintenance: Activated carbon filters need to be changed every 3 to 6 months, depending on usage, to maintain their effectiveness.

Extractor hoods offer several advantages for your kitchen:

• Improved air quality: They eliminate unpleasant cooking odors, fumes and grease, resulting in fresher and cleaner air.
• Protection for furniture and walls: By extracting grease and fumes, it is prevented that grease deposits form on walls and furniture, which simplifies cleaning.
• Comfort: A range hood ensures a pleasant and clean cooking environment that does not obstruct the view while cooking.
• Visibility: The steam is removed, so you always have a clear view of your pots and pans while cooking.

Range hoods are essential appliances that ensure clean and pleasant air in the kitchen. Whether you choose an exhaust or recirculation model depends on the specifics of your kitchen. Regular maintenance and cleaning of the filters ensures that your range hood always functions optimally and that your kitchen remains consistently clean
